JT makes it from special steel alloys for MX, enduro and off-road use where a light, low drag chain matters more than sealed longevity.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003eUniversal 520 - 120 Link\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNOTE:\u003c\/strong\u003e This is a 520 chain, so check your chain size first: many e-motos and e-minis run 420 or 428 chains.\u003c\/p\u003e\n\u003cp\u003eA non-seal chain has no O-rings between the plates, so it runs with less drag than a sealed chain and is easier to clean and re-lube after a muddy ride. The trade-off is more frequent lubing and adjustment, which is why the HDR is a race and practice chain rather than a set-and-forget one.\u003c\/p\u003e\n\u003cp\u003eJT rates the 520 HDR at 8157 lb (36.3 kN) tensile strength and lists it for off-road engines to 350 cc and street engines to 200 cc. Chain size 520, 120 links, steel, non-seal, clip master link, 1.47 kg per 100 links by the maker's figure. Cut to the length your sprockets need.\u003c\/p\u003e","brand":"JT Chains","offers":[{"title":"Default Title","offer_id":67874412069093,"sku":"JTC520HDR120SL","price":42.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0511\/3964\/1496\/files\/jt-520-hdr-competition-chain-steel-120-links-1.png?v=1792846455","url":"https:\/\/gritshift.com\/fr\/products\/jt-520-hdr-competition-chain-steel-120-links","provider":"GritShift","version":"1.0","type":"link"}
